Each outcome in columns (2) to (5) is a dummy variable equal to one if the two MPs in a pair share the same value for the following variables: (2) dummy variable equal to one if MP is male, (3) dummy variable equal to one if ever held a ministerial position prior to this session, (4) dummy variable equal to one if chaired a committee at any point during the previous session, and (5) constituency. The outcomes in columns (6) to (9) are the absolute difference between the two MPs in a pair for the following variables: (6) age in years as of the start of the current session, (7) number of sessions since first session as Althingi member, (8) wages received in Althingi during the calendar year prior to the current session, and (9) expenses claimed in Althingi during the calendar year prior to the current session. The waves and expenses data are only available from session 136 (2008/9) onwards. Neighbor is a dummy variable equal to one if the MPs in the pair are randomly assigned to sit next to each other during that session. Same Party is equal to one if both MPs in the pair are in the same party for that session. Dyadic-robust p-values are in square brackets. Randomization inference p-values (1000 draws) are in curly brackets. Special sessions and a short session (2017) are excluded. Strata FE are dummy variables for whether both MPs in a pair were pre-assigned seats, one MP in a pair was pre-assigned a seat, or neither MP in a pair was pre-assigned a seat. *** p<0.01, ** p<0.05, * p<0.1.} \\ \end{tabular} }
